CVE-2023-5846Network attack vector

Unauthenticated administrator access via decodable credential hashes

Published Nov 2, 2023 · Updated Sep 12, 2024

Weak password hashing in Franklin Fueling Systems TS-550 and TS-550 EVO before 1.9.23.8960 lets remote attackers decode administrator credentials. Published advisories do not identify the credential store, hash construction, or work factor that permits offline decoding. No authentication or user interaction is required, and recovered administrator credentials grant access to the fuel-management console.
